[Bug] Auto-approve permissions is not sticky for long autonomous runs — agent stalls on permission prompt without the user noticing #51398

Description

I run OpenCode for autonomous, multi-step coding tasks (think: 30–60 min agent runs where I walk away). The auto-approve toggle is exactly what I need in theory — but in practice it silently breaks during a long run, and the agent stalls on a permission prompt that I never see. I burned 60 minutes on a run before I caught it.

This looks like it overlaps with three existing reports (#27487, #20998, #31137) but those each cover a single piece. The user-visible shape is the same in all of them: "I asked for auto-approve, OpenCode still asked me."

Steps to reproduce

1. Open OpenCode Desktop (or Web UI).
2. Settings → General → turn ON Auto-accept permissions (the same toggle as the command.permissions.autoaccept.enable i18n key, surfaced in packages/app/src/components/settings-general.tsx:320 and packages/app/src/components/settings-v2/general.tsx:76).
3. Open a session and kick off a long autonomous task (e.g. a multi-file refactor, or anything that touches >1 tool that would normally prompt).
4. Walk away (this is the point — autonomous).
5. Wait. Depending on which surface you're on, one of:
   • Page refresh / app restart → toggle resets to OFF ([Bug] Auto-approve permissions toggle resets to OFF after restart #27487)
   • "New project" layout → toggle is disabled / not associated ([Web UI] "Auto-accept permissions" button is disabled when "New layout and design" is enabled. #31137)
   • Background page while server-side task is running → pending permission requests never auto-accept (fix(app): pending permissions are not auto-accepted after page refresh #20998)
   • Per-session toggle was removed in v1.4.0 ([FEATURE]: Restore per-session auto-accept permissions toggle in Desktop UI #21578) so you can't re-grant it mid-run
6. Agent blocks on a permission prompt. You don't see it. Task sits idle.

Expected

For an autonomous run, the auto-approve decision should be sticky and authoritative for the duration of the session — i.e. once granted (globally or per-session), it survives restarts, page refreshes, and "new project" layout transitions until I explicitly turn it off.

What I checked in the code

• The --auto flag already exists on both tui and run commands (packages/opencode/src/cli/cmd/tui.ts:108 and packages/opencode/src/cli/cmd/run.ts:244) but is documented as "dangerous!" and not surfaced in the Desktop/Web UI as a one-click equivalent for non-CLI users.
• The Web UI toggle is wired through data-action="settings-auto-accept-permissions" (packages/app/src/components/settings-general.tsx:323, settings-v2/general.tsx:79) and an e2e regression test exists at packages/app/e2e/regression/remote-session-settings.spec.ts — so the team clearly cares about this code path, but the persistence story is fragmented.

• [FEATURE]: Restore per-session auto-accept permissions toggle in Desktop UI #21578 — per-session auto-accept was removed in v1.4.0

Suggested fix direction

1. Make the auto-approve decision a first-class persisted session/workspace config (not a UI-only toggle).
2. Reconcile the three surfaces (CLI --auto, Desktop settings, Web UI settings) so they read/write the same source of truth.
3. On session boot, replay any pending permission requests against the persisted decision instead of waiting for fresh user input.
4. Re-introduce a per-session override (the v1.4.0 regression) for users who want strict mode inside an otherwise permissive workspace.
